2 to 18GHz Instantaneous
Frequency Measurement Unit
DR024-F2
2 to 18GHz Instantaneous Frequency Measurement Unit
The DR024-F2 uses proprietary Teledyne Defence technology
to provide state of the art performance in a package measuring
152mm x 147mm x 30mm weighing 1.45kg.
The DR024-F2 is an externally triggered IFM, providing a digital
12-bit output word of the RF input with every sample. The
internal analogue bandwidth is sufficient to capture a 50ns
pulse.
With a resolution of 12 bits, the DR024-F2 gives a nominal
frequency resolution of 3.93MHz and an rms accuracy of
4.5MHz with an SNR of 3dB or better.
Designed specifically for fast jet applications this product will
withstand the most demanding of environments. It is
characterised for –40ºC to +85ºC. For applications outside this
range, please contact the Sales Dept.
External connections are made via a 51 way high density D type
for power and digital I/O and SMA for the RF input.
This product is recommended for new designs. Other IFM
configurations are available; please contact the Sales
Department for further information.

Nominal frequency resolution is unambiguous bandwidth divided by number of bits.
See timing diagrams.
Minimum SNR required for nominal operation.
Minimum pulse width is defined by internal video bandwidth.
Given as the maximum time required between the removal of a pulse of RF at any power within the operating dynamic
range and the arrival of the next pulse to ensure the correct measurement of the second pulse.
6. The actual resolution, i.e., the change of frequency required to change 1 bit of the output word varies with frequency. The
rms accuracy is calculated as the standard deviation of the frequency distribution. The rms accuracy is specified for 3dB.
The rms error excludes those measurements that are flagged as “bad data”.
7. The percentage number of measurements that exceed the peak error frequency.
8. The percentage number of measurements that cause the “bad data” signal to be asserted.
9. Simultaneous signals are defined as signals which overlap by at least 30ns during a measurement cycle.
10. A valid measurement will be made on the larger of two signals provided that a) the amplitude difference between them is
10dB and b) there is at least 100MHz frequency separation.
11. Maximum input power without damage.
